If you have been arrested or charged with DWI in Texas, this is a serious crime with significant penalties. It is important to act immediately in order save your driver’s license and preserve your individual freedom. The State of Texas will bring two different DWI cases against you, a criminal case and an Administrative License Revocation Hearing (ALR). The ALR hearing directly effects the status of your driver’s license and you ONLY HAVE 15 DAYS from the arrest date to request a hearing on the status of your driver’s license. In order to help save your license, you need to request this hearing.

The DWI criminal case may or may not end up going to trial. This largely depends on the court the case is assigned to, the prosecutor, and the evidence that has been accumulated. Andrew will acquire evidence from ALR Hearing, the offense report, any available patrol car or body cam video, and the reason why some of the video may not be available. This information will be crucial in attempting to dismiss the case, come to a reasonable agreement with the prosecutor, and attempt to win at trial.

In the event your DWI case is not dismissed or dealt with prior to trial, your case is headed to trial where the evidence proving your side of the case will be heard by a jury of your peers. Because the stakes are high, the evidence can be complicated, and the science behind breath/blood tests is not always well understood by prosecutors; it is important to hire an attorney capable of explaining the evidence and these issues to a jury in simple and straightforward manner.

Additionally, he is passionate about helping you with Expunctations and Record Sealing of past criminal charges. Having been arrested before, even if that arrest did not result in a conviction, can follow you forever. It may prevent you from getting a job, school admission, loan, passing a background check, or lease. Texas provides a mechanism for many of these types of cases to be removed from the record. This is called expunctation, or sometimes expungement. Not all charges are eligible for expunctation, and a criminal defense attorney can help you determine if you qualify for an expunctation.

Even if you entered into a deferred adjudication, and an expunctation cannot be performed, it may still be possible to have the record sealed. This is called an order of non-disclosure and can be used to keep the record, subject to the deferred adjudication, from being disclosed to the public. It is still possible for certain criminal justice agencies to access the records, but will not be available to the general public.

The internet, and even some FFL SOT (sometimes referred to as “Class 3”) dealers, are full of incorrect and misleading statements regarding gun trusts and not every lawyer even knows what needs to be in the gun trust document itself. Under no circumstances, should anybody use off the shelf forms, or internet "fill in the blank websites," to create a trust designed to hold NFA firearms.

Please use a gun trust lawyer to draft an NFA gun trust, your freedom and your Second Amendment rights may depend on it.
